This is the blurring effect of mobile phone photography, which is caused by the large aperture of mobile phone camera. The front object is clear when the focus is on the front object, and the back object is clear when the focus is on the back object. The larger the aperture of the mobile phone, the more blurred the effect. See if you are using portrait mode. Portrait mode will highlight the blur effect, but photo mode will not.

Aperture is the most important factor to determine the depth of field. Small aperture (large aperture value), depth of field, large aperture (small aperture value), depth of field! For example, nearsighted friends, if they don't wear glasses, always habitually squint at things, so they can often see things clearly. Applying photographic terminology, this is called: narrowing the aperture (pupil) and increasing the depth of field.
